Maytag Oven Error Code 3d51

Error code 3d51 means the UH control board has detected that the meat probe calibration value is outside the acceptable range. This code is specific to Maytag ovens equipped with the UH control. The board checks the calibration data it stores for the meat probe, and when that data fails the check, it displays this fault. The control board is the most likely failed component.

You can generally continue using the oven's standard bake and broil functions while 3d51 is active, since the error is specific to the meat probe calibration system. However, you should not rely on the meat probe to monitor food temperatures while this code is present, as the readings may be inaccurate or non-functional. Resolve the fault before using the probe for food safety reasons.

The meat probe can contribute to error code 3d51 if the probe's output falls outside the range the UH control board expects during its calibration check. However, since the calibration value is stored internally on the control board, a failed board is the more likely cause and the recommended first replacement. If swapping the control board does not clear the fault, test or replace the meat probe and inspect the probe port wiring before assuming further diagnosis is needed.

The first and primary fix for error code 3d51 is replacing the UH control board. Because the calibration value is stored and managed by the control board, a failed or corrupted board is the most common cause. If replacing the control board does not resolve the fault, inspect the meat probe itself and the wiring between the probe receptacle and the board for damage. A replacement meat probe is a lower-cost secondary step if the control board swap does not clear the code.

A replacement UH control board for a Maytag oven typically costs between $150 and $350 for the part alone, depending on the specific model. If you hire a technician, labor costs generally add $100 to $200 on top of the part price. Replacing the control board is a moderately involved repair requiring electrical disconnect and careful handling of wiring harnesses; experienced DIYers can complete it, but those unfamiliar with appliance electronics should have a technician handle it.
